TheirStack vs Sumble

TheirStack and Sumble are both powerful platforms that transform job postings into actionable sales intelligence and technographic data.

TheirStack has been collecting data since 2021, is bootstrapped and profitable with thousands of customers. We've put a big effort in building a world-class self-serve experience for people to use our UI, API and webhooks in an autonomous way. Our transparent public pricing already includes big volume discounts that will let you scale as you want without having to engage in long sales process or be locked into long, expensive contracts.

Sumble is a more recent player that has raised almost $40M in venture capital, with a sales motion focused on enterprise customers. Their product is fast and capable, but smaller in data volume and freshness when it comes to jobs and organizations than us. Even though Sumble has a basic pricing page, knowing costs if one needs more volume than what their $99/month plan offers is not clear will require talking to sales.

Head-to-head at a glance

Pricing Drill-down

1. Transparency and Scaling: No Sales Calls Required

TheirStack's public pricing shows exactly what you'll pay at every level. As you scale, the cost per credit drops dramatically—down to $0.0015 per credit on our $1,500 plan. You can scale from 1,500 to 1,000,000 credits autonomously.

Sumble's Pro plan (check their pricing here) provides 9900 credits for $99/month. Once you need more, there is no other option than to contact sales for an Enterprise plan.

Conclusion: TheirStack wins on pricing transparency and self-serve scaling.

2. Job and Organization Costs (API Credits)

At TheirStack, a job costs exactly 1 API credit. An organization lookup costs exactly 3 API credits.

TheirStack also have webhooks, which is the equivalent of Sumble's signals. The cost of getting data via webhooks on TheirStack is the same as via API (1 job = 1 API credit, 1 company = 3 API credits). On Sumble, what you can get via signals is limited to 20/day with their Pro plan, so you can only get up to 600 signals per month.

Sumble charges 3 credits per job (~$0.03 with their Pro plan). The closest plan TheirStack has in price offers 5k API credits for $100/month. For the same montly spend, TheirStack gives you:

• Up to 5k jobs
• Up to 1,666 companies via webhooks (what Sumble calls signals)

On the other hand, Sumble gives you:

• Up to 3.3k jobs
• Up to 600 signals (600 companies)

Conclusion: TheirStack wins on job and organization costs.

3. Technographics cost: Fixed vs. Variable

This is where the difference is most extreme.

• TheirStack: A single lookup (3 API credits) returns every technology we have ever identified for an organization, along with confidence levels and granular metrics.
• Sumble: They charge 5 credits for every single technology found.

The Price Equivalency: If you enrich an organization that uses 20 technologies:

• Sumble: 100 credits = ~$1.00
• TheirStack: 3 credits = $0.0045 – $0.11

TheirStack is up to 200x more cost-effective for technographic enrichment at scale.

Conclusion: TheirStack wins on technographics cost.

4. UI Pagination and Search Limits

Sumble's "Pro" plan caps your search results at 10 pages. TheirStack is fully usage-based and provides infinite pagination in the UI—as long as you have the credits to view the data, you can access it.

Conclusion: TheirStack wins on UI pagination and search limits.

Data Volume and Freshness

When it comes to the sheer volume of data and how quickly it's delivered, TheirStack consistently outperforms Sumble across both jobs and organization profiles.

Job Volume: 4x More Coverage

TheirStack identifies over 2,000,000 jobs per week, which is over 8M jobs per month. Click here to open this search on TheirStack to double-check it yourself.

Sumble only surfaces approximately 1,800,000 jobs per month. This gives TheirStack over 4x more volume than Sumble. Double-check by going to this same search in Sumble.

Conclusion: TheirStack wins on job volume.

Job searches filtering by technology

Both TheirStack and Submle identify technology usage from mentions in job posts. So both of them should be great at being able to surface jobs that mention specific technologies. Let's see how true that is.

For a search like "Python jobs posted in the last 30 days", TheirStack identifies over 224,000 jobs, as seen in the folllowing screenshot. Open this search on TheirStack

On the other hand, Sumble only yields approximately 125,000 jobs for the very same search. Open this search on Sumble

Real-time Freshness

TheirStack processes and exposes jobs in our API and UI within minutes of them being posted online.

In contrast, Sumble can take up to 24 hours to surface the same listings. See this checking the Time column of the picture above.

Conclusion: TheirStack wins on data freshness.

Database Scale: 9.5M vs 2.7M Organizations

• TheirStack: Detailed data on 9.5 million organizations.

  

• Sumble: Data on 2.7 million organizations.

  

TheirStack has 3.5x more organizations in its catalog.

Conclusion: TheirStack wins on organization volume.

Data Depth and Feature Nuances

To provide an objective comparison, it's important to recognize where each platform focuses its engineering efforts. While TheirStack prioritizes the breadth and depth of job data and technographics, Sumble has invested more heavily in the "Person" and "Team" layers of sales intelligence.

Person-Level Intelligence

Sumble includes person-level data, which allows them to offer signals that TheirStack currently does not. For example, they can track when a company increases headcount in a specific area by monitoring changes in LinkedIn profiles.

If your workflow requires identifying the specific individuals currently at a company or seeing headcount trends based on existing employees, Sumble has a clear advantage here. TheirStack focuses exclusively on the "Organization" and "Job Posting" level—we tell you who they want to hire, not who they already have.

Conclusion: Sumble wins on person-level intelligence.

Team and Department Mapping

Sumble also attempts to identify and map specific teams within a company. This can be useful for seeing how an organization is structured internally. TheirStack provides granular firmographics and technographics for the organization as a whole, but we do not currently provide a structured breakdown of internal departments or teams.

Conclusion: Sumble wins on team and department mapping.

Job Title Normalization

Sumble uses machine learning to normalize job titles, which can help group similar roles together (e.g., "Software Engineer", "SWE", "Software Developer" might all map to a standardized title). TheirStack does not currently perform job title normalization—we return job titles as they appear in the original job postings.

Conclusion: Sumble wins on job title normalization.

Technology Inference: "Used" vs "Mentioned"

Sumble attempts to infer which technologies are actively used versus which are just mentioned as nice-to-haves in job descriptions. They label technologies as either TECH USED or TECH MENTIONED to help users understand what's required versus what's optional.

However, this inference is very unreliable and fails at basic logical relationships. For example, Sumble may mark a JavaScript framework like D3 or React as TECH USED while simultaneously marking JavaScript itself as only TECH MENTIONED. This is logically inconsistent—if a JavaScript framework is used, then JavaScript knowledge is absolutely required as well. The system fails to recognize these fundamental dependencies between technologies.

TheirStack takes a different approach: we identify all technologies mentioned in job descriptions without attempting to infer usage versus mention. We focus on doing one thing well—accurately identifying what technologies appear in job postings—rather than trying to do more and doing it inconsistently.

Conclusion: TheirStack wins on technology inference reliability.

Technology Catalog Quality

Sumble's technology catalog is derived directly from job descriptions using a Named Entity Recognition (NER) model. While this approach can capture a wide range of terms, it yields many entries that aren't actually technologies. A very large percentage of Sumble's catalog consists of "dirty" technologies—phrases like "Python Data Analytics", "Python backend", "Python software development", "Data visualization using Python", and "API/Python" that are descriptive phrases or job functions rather than actual technology names.

TheirStack's technology catalog is smaller and cleaner because it doesn't contain this fluff. We focus on identifying actual technologies mentioned in job postings, not extracting every phrase that happens to contain a technology keyword. This results in a more accurate, usable catalog for filtering and analysis.

Conclusion: TheirStack wins on technology catalog quality.

Organization Intelligence and Parent-Subsidiary Relationships

Founded by world-class Machine Learning experts, Sumble does a much better job at organization intelligence, particularly in identifying and mapping hierarchical organizational structures. They can accurately determine whether an organization has subsidiaries or is an independent company, and they effectively tie together organizations under the same parent organization.

For example, Sumble can display complex hierarchies like "U.S. Government" → "US Department of Energy" → "Lawrence Berkeley National Laboratory" → "Cyclotron" with clear parent-child relationships. This hierarchical view helps users understand organizational structures and relationships at a glance.

TheirStack treats organizations more independently and does not currently provide the same level of parent-subsidiary relationship mapping or hierarchical organization intelligence.

Conclusion: Sumble wins on organization intelligence and parent-subsidiary relationships.

API Documentation and Filtering Capabilities

Developer Experience: Clear Documentation vs. Limited Docs

TheirStack's Job Search API documentation is comprehensive, self-serve, and includes examples for every parameter. You can test endpoints directly in the browser.

Sumble's API documentation is more limited. While functional, it lacks the depth and clarity needed for complex integrations. Understanding parameter usage often requires trial and error or reaching out to support.

Sumble offers an "advanced query" option that allows filtering by fields like job_function or hiring_period, but these parameters are not documented in their public API reference. This undocumented functionality requires developers to discover features through experimentation or support conversations.

Filter Depth: 40+ vs. 7 Filters

This is where the gap becomes most apparent for developers building sophisticated search workflows.

TheirStack's Job Search API offers 40+ filters across multiple categories:

• Job-level filters: Title (with regex support), description patterns, location patterns, salary ranges, seniority, remote options, posted date ranges, and more.
• Company-level filters: Industry, size, country, revenue, funding, URL patterns, LinkedIn URL, and more.
• Technology filters: Filter by technologies mentioned in job descriptions.
• Advanced features: Regex support for many text fields, exclusion filters, and complex boolean logic.

Sumble's Jobs API offers just 7 filters according to their public documentation:

• Company filters (domain, ID, slug)
• Technology filters
• Technology category filters
• Country filters
• Date filters (since)

Notably, Sumble's API doesn't even support filtering by job title according to their public documentation. This is a fundamental limitation for many use cases where you need to find specific roles (e.g., "Data Engineer" or "DevOps Manager").

If you need to build sophisticated search workflows—like finding "Python jobs in New York posted in the last 7 days for companies with 50-200 employees"—TheirStack's extensive filtering capabilities support this use case.

Conclusion: TheirStack wins on developer experience.
